Mix together the chicken, egg, parmesan, salt, pepper, oregano, and garlic powder in a medium bowl.
Cover a pizza pan or sheet pan with parchment paper. Place the chicken mixture in the center of the paper and pat into a 10 to 12-inch diameter circle. It will be about 1/4 thick. When you remove the garlic from the oven, put the crust in to bake for 20 minutes.
Chop the tomato and parsley and halve the olives and set them aside. Once the garlic has cooled, squeeze the cloves into a small bowl or ramekin.
When the crust is finished, take it out and drizzle it with the olive oil. Top the pizza with the Italian cheese blend, then the olives and garlic, and finally the goat cheese. Put back in the oven for 10 minutes. Remove, top with the tomatoes and parsley, and serve immediately. If you won't be eating it all, save some tomatoes and parsley to top the pizza with after you reheat it.
